f Application led March To all whom t may concern.'

Be it known that l, l-lUs'roN TAYLOR, a citizen of the United States, and a resident of Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful improvements in Fanxlulleys, of which the followingis a full, clear,

` and exact description.

' The invention relates to pulleys and fans l@ for cooling internal combustion engines used on vehicles.

Theobject of the invention is to provide a pulley of this character with improved .v lubricating means and an'improved means the fan and pulley together. The invention consists in the several novel features hereinafter 'set forth and more particularly defined by claims at the conclusion hereof. v

ln the drawings: Fig. 1 is an axial section of a pulley and fan embodying the invention. Fig. 2 is a face view of the fan and pulley. Fig. 3 is ai section on line 3-3 of Fig. 1. Fig. t is a section of a modiied .formiof the invention. Fig. 5 is a section on line 5+5 of Fig. 4.

The pulley 7 is mounted upon a spindle 8. which is adapted to be'connected to, and 'supported by, a suitable bracket 6 being 3e usually provided with a screw-thread at one end forthat purpose. The pulley is provided with a body having a grooved periphery formed by flanges 9 for a belt to drive the pulley and fan. The pulley has end' walls 10 and inwardly extending hubs 11 integral with the periphery or body. rllhe spindle 8 has a shoulder 12 and a washer 13 held by a nut 14, and the pulley is held against longitudinal movement by said shoulder and washer.

The pulley is formed with an integral boss projecting from its outer end and a fan consisting of crossed blades 16 and 1 7. ln the fan shown, `there are plural blades longitudinally and slightly in rotative advance of one another and spaced apart by rivets 13 and a sleeve 19. A cap-nut 20 screw-threaded to the end of boss 15 is adapted to clamp the hubs cf the fan-blades and sleeve 19 against a shoulder 21 to secure the entire fan on, and for rotation with, the pulley and also serves to close vthe outer end of the boss 15.

deflect/sr 22 integral with the pulley is e 'proyidec between each hub 11 and the body c.' 'el 1920. Serial No. 364,025.

25 of each deflector 22 adjacent a hole 26is' rotation of the A disshaped so that it will, during pulley, direct the oil to sa1d hole. tributor groove 27 is formed in each hub 11 and extends to the inner end thereof. The periphery 28 of the chamber 23 is flared from its center to equally distribute the oil to the deectors. 'llhe pulley is provided with aA portion 31 to counter-balance the plug 24.-. rlhe holes 26 are disposed in rotative advance of the defiectors 22. For convenience in manufactureTof pulleys for either right or left drive, both faces 25 of the deflectors are formed to carry the lubricant inwardly 'to the hubs, so that by forming the holes on either side of the deflectors, the lubricating means will be operative according to the direction in which the `pulley is driven. A. packing ring 33l is provided at the inner end of the pulley to prevent the escape of lubricant. rThe outer end of the pulley being closed by cap, no packing is necessary for the outer hub 11. rlhe deflectors are disposed on opposite sides 'of the spindle to counterbalance one another. y

ln operation, the rotating deflectors will forcibly feed the lubricant to andthrough the holes 26 to the spindle and so that the bearing surfaces between the spindle and .the pulley will be flushed by the oil forced between said surfaces.

ln the modification shown in Figs. l and 5, the pulley 7 is provided with one hub 11 extending inwardly from one end of the pulley and two oppositely disposed dellectors 22 similar in shape and function te those shown in Figs. 1 and 3 are formed between the periphery of the oil chamber 23i and said hub. Holes 26 are formed in rotative advance of said deiectors to force the oil to the bearing surfaces as herein aforesaid. An oil inlet closed by a plug 251 also is provided in this modification. YThe outer end of the chamber 23 extends to the outer end of the pulley and is there closed by the fan. Bolts 33 extend through the hubs of the fan-blades 16 and 17, spacers 32 and a packing ring 341 to clamp them all to the outer end of the pulley, a packing-ring 35 is i ety provided at the inner end of the pulley. A

Ahead 8L on the outer end of the spindle holds the pulley against outward movement on thel Spindle. An abutment disk 36 on the fan holds the vpulley against inward movement onthe spindle.

' The invention is not to be understood as 4restricted to the details set forth, since these yl claim as new and desire to secure by 'Letters Patent, is:

1. The combination of a spindl'e, and a pulley rotatable on the spindle andcompris ing a body having ai closed chamber therein adaptedto lretain lubricant, a peripheral wallsurrounding the chamber, a hub in the chamber having a hole leading to the spindle, and a delector wall integral with the body extendingentirely acrossthe space betweenl the peripheral A surrounding wall and the hub and sloping inwards towards the axis of the spindle to force the lubricant to said hole when the pulley is rotated.

2. rlhe combination of a spindle and a pulley rotatable on the spindle and comprising a body having a closed chamber therein and a peripheral wall and a hub in the chamber having a hole leading to the spindle, and a dei'lector wall integnaLwith the body extending entirely across the space between the hub and the peripheral wall and having portions sloping inward towards the axis of the spindle to force the lubricant to said hole during rotation of the pulley in opposite directions respectively.

3. rhe combination of a spindle and a inflate@ pulley, rotatable on the' spindle and comprising'a body having a chamber therein-` means. to supply lubricant to said chamber,

means to close the ends of the chamber, in-

ends of the pulley. A

4. The combination lof a spindle, a pulley rotatable on said spindle, and a lfan, comprising blades, the pulley comprising a body having a chamber therein and closed ends, means'in the pulley to force lubricant towards the spindle and a boss lon the pulley; extending through the fan-blades, and a nut en the. boss for clamping the blades on the pulley,

5. lhe combination of a spindle, a pulley rotatable on said spindle, and a: fan comprising blades, the pulley comprising a body having a chamber therein, and closed ends,

means in the pulley to force lubricant towards the spindle, a boss on the pulley extending through the vfan-blades, and -a capnut on the boss for clamping the blades on the pulley and extending over the end of the boss.

6'. The combination of a spindle, a pulley rotatable on saidspindle, and a fan comprising blades, the pulley comprising a body having a chamber therein and closed ends, a hub in the body having a hole therein leading to the spindle, a deiector having a surface to force lubricant to said hole.
